Windows7 system switching dual sound card method

1, if it is Bluetooth audio rendering as a sound card, then first link Bluetooth headset (or speaker), the system will automatically download the corresponding Bluetooth audio rendering driver, this time you can see in the device To the corresponding Bluetooth driver;

2, then right click on the volume icon in the lower right corner of the taskbar, select the volume control option, and you will find the “Bluetooth audio rendering program” in the sound device. Then check the Bluetooth audio rendering program and speakers;

3, then you can set the default playback device on the sound settings page, if you just link the Bluetooth headset, Bluetooth will become the default device, so after the Bluetooth headset is connected The speaker will automatically go to the Bluetooth headset without sound. Here we can set the default device as the speaker, right-click and select to set to default, then all the sound will return to the speaker.

4, then open the video player software, here must choose some broadcaster software that can set the audio output, there are a lot of software can not set the audio output device, video personally like to use KMplayer, audio with foobar2000.

Take KMPlayer as an example (other methods for setting audio output are similar), first open the player, right click and select “Audio-> Audio Renderer-> Bluetooth Audio Rendering Program”; Br>

5, after setting, the sound of the KMPlayer player is output to the Bluetooth headset, and the sounds of games, music, etc. on the computer are left on the speaker. Is it amazing?
